METALLIC C'ULVERT.

Specification of Letters Patent.

Patented Aug. 2'7, 1907.

Application tiled April 10,1907. Serial No. 367,429.

s E. \l'ix'rnoms, a citizen ibihe United tates. residing at Huntington, in the c hntv of Huntington and State of Indiana. have in- ;fii-ted certain new and useful improvements in Metallic 'ulverts: and I do hereby declare the following to be a. full. char. and exact description of the invention, such as will enable others skilled in the art to which it APPOD tains to make and use the same.

My invention relates to improvements in metallic ii-ulvcrts. and the object otzny invention is to form a ClllVtit ol' corrugated metal plates. bent to form circular sections. the ends of adjacent sections being firmly secured togethetx Zach of the pipe sections may be made of a single corrugated plate bent so as to forum tube and having riveted together. or it may be made ol' a number of'such plates ha ving their tn.'eila ping edges riveted together and the whole bent into the form of a tube.

its edet l urther objects will appear in the detailed description.

With this ohjectin view. my invention consists in the con ruction and combinations of parts ashereiualter desi-ri bedand claimed.

in the accolnpai'iying drawing-l igure l is a perspectherefor. v

n represents one of the pipe sections, .made of corrugated sheet metal plat bent into approximately c rcular form, the edges overlapping and riveted together by rivets I1. One end of each section is left um'ivcted that it may he slipped over the end of the adjacent so that one or two corrugations overlap. as iQWil n l-ig. drawn tightly against the end of the adjacent section by any suitable means such as a chain or rope passed a mud the secti n, tne'ends of said chain or rope ,lu-ing drawn together by a lever. "tivets c are then passed tl'n' ugh the o'verlappinu section ends. and the scam heatled-holding the sections tirnily'together.-

To still further strengthen the structure I employ binding piec or stri tlnvmgh each of which three or more rivet. are p ed and headed, tlitycreiitral one liil'fltltfit tilt. strip and both sections and the outer ones throw l the strip and one of the sections, theserivets b i lettered andfand g.

:cction of one of the ends of a section. showing strengthening means The unriveted end of a section is then in some cases I employ additional fastening means,

it represents a corrugated circular pipe. smaller than the pipe sections and adapted to fit therein. The ends ol' two pipe sections are brought. together, each overlam'iingthe shorter and smaller pipe sections. The binding pieces dare then placed in posii verlapping the ends of the main pipe sections and rivets i. i and I. headed through said binding pieces and the interior pipe, some of these rivets passing through the main sect ions. binding the whole firmly toget her.

,It should be noted that a complete culvert: could be made up of separate pipe sections with their ends overlapped and riveted together. and that. such a construction is a practical and useful one. The binding strips or the inner tube described are used only as an extra precaution. At theendsofthepipc, so built ttpoisections, 1 provide strengthening pieces shown in Fig. 5; which consist of an angle iron I having a flat annular lace m, the angle iron being shaped to ill. the corrugation at the end of a pipe section and riveted thereto.

Having thus described my invention, what I claim as new and desire toseeure by Letters: Patent otthe United States, is:-

1. A culvert made up of sections. said sections being composed ot' corrue'atcd metal plates bencinto the form of a tube and having their edges: riveted together. the ad jacent ends. of said sections overlapping" each other and riveted together. substantially as described.

1!. A metallic culvert composed of sections made of cor-,

rugated metal plates bent into tubular form and having their edges riveted together. said culvert'being made up ol :1 number of -saidpipe sections and said pipe sections oven-lapping: each other at their adjacent ends, binding pieces over said overlapping ends, and rivets passing through said binding pieces and said overlapping ends, substaiitlally as described.

3 metallic rulvert made up of sections composed of corrugated metal plates bent into tubular form and having their edges riveted together. said culvert being made up of a number of pipe sections, and binding pieces riveted to the cm at adjheent pipe sections, substantially as described.

-l.-.\ n tallic culvert made in sections, composed of corrug-aurd plates bent into the shape ot-a tube and having their edges riveted together, means for fastening said sec-- lions firmly together, and strengthening means for the end of said culvert, con. iug of an annular angle iron rivete'l oreto and having one of its angles shaped to conl'orm to the shape of the adjoining corrugated end of the end pipe section, substantially as deseribed.

in testimony whereof, I aiiix my signature, in presence of two witnesses.
